When finding an integer you figure out if the integer is positive or negative; positive as in being above a certain point, such as sea level, and negative as in being below that certain point. Being positive might also mean going up or moving forward; and vice versa for being negative.

1. 282 feet below, so it is -282

2. 3 inches more, so it is 3

3. gained 5 points and lost 4 points, so 5 & -4

4. The airplane pilot could have gone down in altitude by 100 meters, or could have gone up in altitude by 100 meters.

Given:

$d(t)=80t$

$C(d)=0.09d$

To find:

The value of $C(d(10))$ .

Solution:

We have,

$C(d(10))=C(80(10))$ $[\because d(t)=80t]$

$C(d(10))=C(800)$

Now,

$C(d(10))=0.09(800)$ $[\because C(d)=0.09d]$

$C(d(10))=72$

Therefore, the value of $C(d(10))$ is 72.

Mrs. Robinson, an insurance agent, earns a salary of $4,800 per year plus a 3% commission on her sales. The average price of a p

Answer:

Required inequality is $4800+183x>8000$ .

Step-by-step explanation:

Given that Mrs. Robinson, an insurance agent, earns a salary of $4,800 per year plus a 3% commission on her sales. The average price of a policy she sells is $6,100. Write an inequality to find how many policies Mrs. Robinson must sell to make an annual income of at least $8,000.

Calculation is given by:

Salary per year = $4,800

Average price of a policy = $6,100.

commission on her sales = 3%

Then commission on $6,100 = 3% of $6,100 = 0.03 ($6,100) = $183

Let number of policies Mrs. Robinson must sell to make an annual income of at least $8,000 = x

then total commission on x policies = 183x

Total income using x policies = 4800+183x

Since she wants to make an annual income of at least $8,000. so we can write inequality as:

$4800+183x>8000$

Hence required inequality is $4800+183x>8000$ .

grade 5 math. How would I write a ratio for a project when asked to compare prices from two stores, IE 32 slices of texas toast

REY [17]

To compare, think of the ratios as a fraction. so it is 32 slices per $7.99.
You can also say $7.99 per 32 slices.
so it can be ̲7̲.̲9̲9̲ ̲ or the other way around.
32
To find the unit price, or the price of 1 item, you have to divide the price by the amount.
So 7.99 divided by 32 is 0.249687, but we don't have thousandths of a cent, so we round to the hundredth.
$0.25 is the unit price, or the price of 1 toast, rounded to the nearest cent.

So let's try another one, this time we have 2 different rates, and we will compare them.

So let's say we are buying cheese. Store A sells 12 blocks of cheese for $14.99, and Store B sells 20 blocks for $23.99.
So first we have to find the unit rate for each.

Store A Store B
14.99 per 12 23.99 per 20

 ̲1̲4̲.̲9̲9̲ ̲ ̲2̲3̲.̲9̲9̲ ̲
12 20

14.99 / 12 is 1.24916 23.99 / 20 is 1.1995
$1.25, if rounded to the cent. $1.20, if rounded to the cent
1 block is $1.25 in Store A. 1 block is $1.20 in Store B

Store B sells for cheaper.

Hope that helps.
